What am I looking at? This is a 3D rendering of an RNA polymerase II enzyme from baker’s yeast, created using actual molecular data to reconstruct its shape and active sites. What looks like a ...

However, DNA polymerase cannot begin forming this new chain on its own and can only add nucleotides to a pre-existing 3'-OH group. A primer is therefore needed, at which nucleotides can be added.

A cold sore might seem like a minor nuisance. But behind that tingling lip is one of the world’s most widespread and cunning ...

New imaging tools reveal how within an hour of infection, the virus begins to alter our chromosomes to kick-start its own replication.

STONY BROOK, NY / ACCESS Newswire / June 16, 2025 / Applied DNA Sciences, Inc. (NASDAQ:APDN) (“Applied DNA” or the “Company”), a leader in PCR-based DNA technologies, today announced that it will ...

Researchers discovered that HSV-1 (herpes simplex virus) actively reshapes the 3D layout of human DNA within hours of ...

Many researchers have attempted to tackle this challenge, but they have had limited success. Recently, at the International Symposium on Human Identification (ISHI), scientists at Promega Corporation ...

The researchers have now created a mirror version of T7 RNA polymerase, a highly efficient enzyme that uses more convenient double-stranded mirror DNA templates.

Finally, DNA polymerase extends the primers, synthesizing new DNA strands. This cycle repeats, exponentially amplifying the DNA. Key Components of PCR. PCR relies on several essential components to ...

The Hindu explains how while most organisms prefer DNA over RNA, its chemical cousin, to store genetic information, many disease-causing viruses have benefited from having RNA as a genetic material.

DNA polymerase III is the main family C polymerase involved in E.coli DNA replication. ... These enzymes work by using RNA as template to synthesize a DNA strand. Sources.
